A way to see members of a server who are on your friends list

Although I don't imagine a lot of people would see this as a particularly useful feature, I'm quite fond of the idea that when you either get invited to, or join, a server, there should be a way to see who on your friends list is on said server without having to scroll through your friends list. As previously mentioned, it's not something that I imagine a majority of the community would be interested in, but a few of my friends and I have discussed a feature like this and we think it'd be a cool feature to implement.
